FLOOR WAXING DEVICE Filed March 16, 1932 Gttorncg Patented Nov. 28, 1933UNEEED STATES PATENT OFFICE FLOOR WAXING DEVICE Edward Matthews,Hamilton, Ontario, Canada Application March 16, 1932. Serial No. 599,1122 Claims. (01. 91-s9) This invention relates to floor waxing devices ofthe class wherein the waxing element is reciprocated on the floor to bewaxed. It is intended for use with paste wax.

One important object of the invention is to generally improve uponwaxing devices.

Another important object is to provide a waxing device having a waxfountain and pressure feed.

Another important object is to provide a device of the class specifiedwith means for releasing the feed pressure during filling the fountain.

Yet another object is to provide for an even feed.

Still another important object is to provide a floor waxing device that,when the wax is exhausted from the fountain, is serviceable as apolisher without alteration or adjustment of the parts.

Another object is to provide a device of the kind described which willbe simple, durable, efficient, inexpensive to manufacture, and which maybe marketed at a competitive price.

With the above and other objects in view as will be hereinafterapparent, the invention consists in general of certain novel details ofconstruction and combinations of parts hereinafter fully described,illustrated in the accompanying drawing and specifically claimed.

In the accompanying drawing like characters of reference indicate likeparts in the several views, and:

Figure 1 is a top vi w of a floor waxing device constructed inaccordance with this invention; and,

Figure 2 is a cross-sectional side elevation taken on the line 22 ofFigure 1.

In its present embodiment the floor waxing device comprises the shell 10opening downwardly, and the pressure shoe l1 slidingly mounted in theshell. The pressure shoe is preferably in the form of a plate, thebottom face of which, at least, is even and smooth, and whose areaconforms to the inside dimensions of the shell, the walls of which areparallel.

The shell is provided with an outturned peripheral flange 12 at theopening, A feed screen preferably in the form of a cloth 13 (shown inFig. 2 only) is extended over the opening completely closing it exceptfor the interstices, and the edges of the screen are doubled over theflange 12 and gathered against the lower portion of the shell wallswhereafter they are bound preferably by an elastic band 14. Between thescreen and the shoe, when the latter is drawn within the shell away fromthe opening, is the fountain area for the paste wax. The flange 12 isslightly aoclivous towards its outer terminal as a provision forsledding over an uneven floor.

The shoe is provided with a centrally located pair of parallelspacedstandards 16 extending through conforming perforations in the shell top.These standards are vertically slotted as at 17, part of the slotextending above and part of it below the shell top in each standard.That por- 5 tion of the slot extending below theshell top merges with anotch 18 opening on one edge of the standard.

A cam 19 is interposed between the projecting end parts of standards 16and is provided with 7 opposed axially aligned and eccentrically mountedpintles 20 bearing in the slots 17. The cam bears upon vthe confrontingportion of the shell top and is provided with an operating handle orlever 21.

The cam is adapted to make alternately a onehalf turn. When the cam isin one extreme position the standards are obviously raised to upper deadcenter and the shoe 11, which is carried by the standards, is alsoobviously raised, and when the cam is moved or thrown to the otherextreme position the standards and shoe are lowered. In the drawingthese parts are shown in raised position. When the cam is moved to lowersaid parts the distance is so calculated as to cause the bottom face ofthe shoe and the rim of the shell side walls to even.

Helical expansion springs 22 urge the shoe downwardly. These springsbear. against the shoe and against the inner face of the shell top.Bosses 23 keep these springs in position. When the shoe is flush or evenwith the shell wall rims the springs are fully relaxed and the cam is inone extreme position.

Throwing the cam to the other extreme position raises the shoe underspring urged resistance, but this is quite easily done owing to the longleverage. This extreme position of the cam temporarily locks the shoe inelevated position and removes the influence of the springs. Theprovision of two or more springs equalizes the pressure on the shoe.

The feed screen 13 first being removed, paste wax may now be spread intothe fountain area against the pressure shoe until the level of the waxis flush with the shell wall rims. The device is ready for use when thefeed screen is replaced and fixed, and the cam thrown to the positionmaking the springs effective.

The release of the springs at once causes the 110 wax to commence toooze through the feed screen. Thus the wax is gradually fed to the flooras it is used, and obviously the rate of flow may be predetermined bythe use of a feed screen of proper texture.

The wax will regularly feed until the filling is exhausted, but if it isintended that the work be discontinued before the fountain area is emptythe flow may be stopped by throwing the cam.

When the device is thoroughly empty the shoe, as previously specified,is level or even with the shell wall rim, and in this condition, grantedthat the feed screen is still in position, the de-,

vice may be used for polishing the previously waxed floor.

The notch 18 enables the cam pintles 20 to enter the slots 17 duringassembling. This is accomplished by pressing the shoe well beyond normalrange into the shell thereby bringing the notch on the outside of theshell.

24 are ears mounted on the shell to receive the furcations .of, a handle,(not shown). With the handle removed the device may be used by graspingby the hand, for stairways and the like.

There has thus been provided a simple and efficient device of the kinddescribed and for the purpose specified.

It is obvious that minor changes may be made in the form andconstruction of the invention without departing from the material spiritthereof. Itis not, therefore, desired to confine the invention to theexact form herein shown and described, but it is desired to include allsuch as properly come within the scope claimed.

Having thus described the invention, what is claimed as new, is:

1. In a floor waxing device,.a shell opening downwardly, a pressure shoeslidingly mounted in the shell and having a lower range terminal and anormal upper range terminal, springs mounted in the shell urging theshoe downwardly toward the orifice of the shell, feed means across theorifice, a pair of parallel spaced standards superimposed on the shoeand extending slidingly through individual perforations in the shell topto the outside, a cam interposed between the projecting parts of thestandards, oppositely disposed pintles eccentrically mounted on the camand. bearing in vertical slots in the standards, said slots extendingabove and below the shell top, the cam having camming action againstthat portion of the shell top bridging the main portions thereof betweenthe perforations therein to vary the position of the stanclards, thelower ends of the standard slots merging with notches opening on thevertical edges of. the standards providing access to the slots for thepintles when the shoe is forced beyond its normal upper range terminalmoving the notched portions of the standards to the outside of theshell.
